IMPROVEMENT IN LOCKS FOR PISTOLS, &0.

Specification forming part of Letters Patent No. l87,l35, dated February6, 1877; application filed December 9, 1876.

` tion of the Construction and operation ot' the same, reference beinghad to the annexed drawings, making a part of this specification, and tothe letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a central verticalsection of our pistol, and Fig. 2 is a perspective view of the trigger.

This invention 'relates to improvements in pistols; and consists incertain improvements therein, as will be hereinafter more fully setful'th.

A designates the stock of a pistol, and B the barrel, provided withfront sight b and rear sight b'. C designates a hammer, made in onepiece with, or rigidly attached to, a tumbler, D, having a cock-notch,d, said tumbler being pivoted within the hollow of stock A. E designatesa trigger-guard, made of spring metal, secured at one end to the underside of stock A, and at the other end to a linkbar, F, whereby it islinked to tumbler D, near the line of attachment of hammer O, and at thefront of said tumbler. Gr designates a trigger, protected by guard E,and pivoted in front of and below tunbler D, in the usual manner. Theupper end of said trigger is provided with a curved dog or catch, g,which engages with notch d on tumbler D, so as to hold hammer G atfull-cock when the latter is drawn upward. H designates a spiralreplacing-spring, which sits within a cup or socket, h, of stock A, andbears against the rear side of the lower end of trigger G. When saidtrigger is pressed upon by the finger, in

the usual way, tumbler D is freed from dog g, and guard E, acting as amainspring, operates to throw said hammer O forward, exploding thecartridge. StockAand barrel B are, pret'- erably, constructed in onepiece, ot' metal, and perforated from the hollow ot' the stock outwardon the under, side at A A to allow the play of spring-guard E andtrigger G.

ln order to enable the Operating parts to be placed in the smallestpossible space, the dog or catch g of trigger G is recessed in themiddle part of its end at g', as shown in detail in Fig. 2, whereby thegreater part of the operating mechanism lies within the hollow stock,and is protected from injury thereby.

In cooking, and while hammer 0 is cocked, link-bar F sets into saidrecess g', without interi'ering with the action of trigger G. recessmay, however, he omitted, it' desired.

We are aware th at a cock and tumbler made in one piece, and connectedbya link-bar with BENJ AMIN HAVILAND. GEORGE BEGK GUNN. Witnesses:
